This is a, hopefully, temporary bug...***

"A magical, open-ended children's world, designed by the brothers who went on to create "Myst."
The Manhole is a notable computer game because like Cosmic Osmo and Spelunx it has no goal and no end; the object is simply to explore and have fun.
"Describing The Manhole as "the first children's software to require a hard disk", Macworld
in March 1989 stated that its "realistic sounds, the fantasy-filled
graphics, and the stack construction are truly impressive". The magazine
"highly recommended [the game] for young children[, and] it's hard to
imagine a playful soul of any age who wouldn't enjoy exploring the
mind-tickling world inside The Manhole".
